Sudden olfactory loss as an early marker of COVID-19: a nationwide Italian survey.

PURPOSE: The presence of many asymptomatic COVID-19 cases may increase the risks of disease dissemination, mainly for physicians. There are numerous reports on the frequent findings of sudden anosmia or hyposmia, before or at the same time of the typical COVID-19 symptoms onset. The aim of this study was to verify the association of olfactory impairment and COVID-19, providing a basis for subsequent research in the field of COVID-19 clinical heterogeneity. METHODS: We developed a 15-item online questionnaire on "Sudden Olfactory Loss (SOL) and COVID-19" that was administered during March 2020 to Italian general practitioners registered to a social media group. RESULTS: One hundred and eighty responses were received. SOL was identified as a significant sign of infection in COVID-19 patients, mainly aged between 30 and 40 years, even in the absence of other symptoms. SOL was present as an initial symptom in 46.7% of subjects, and in 16.7%, it was the only symptom. Among the COVID-19 confirmed cases, SOL occurred as the only symptom in 19.2% of patients. CONCLUSION: SOL could represent a possible early symptom in otherwise asymptomatic COVID-19 subjects. Subjects affected by SOL should be considered as potential COVID-19 cases. LEVEL OF EVIDENCE: 4.

The role of endogenous Antisecretory Factor (AF) in the treatment of Ménière's Disease: A two-year follow-up study. Preliminary results.

PURPOSE: To evaluate the effects of increased endogenous Antisecretory Factor (AF) synthesis using specially processed cereals (SPC) in a sample of patients with defined unilateral Meniere's disease (MD), compared to the results of a treatment protocol of intravenous glycerol and dexamethasone. MATERIALS AND METHODS: Twenty-six patients with unilateral MD were divided in 2 groups and treated with SPC and with intravenous glycerol and dexamethasone for 24 months. Audio-vestibular evaluation was performed before (T0) and every six months. The number of vertigo spells were evaluated before and after therapy and the Efficacy Index (EI) was calculated. Questionnaires for hearing loss, tinnitus and quality of life were administered. RESULTS: EI decreased in the SPC group after 18 (T18) (p = .0017) and 24 (T24) months of therapy (p = .0111). There was a significant reduction for tinnitus score in the SPC group at T24 (p = .0131). No significant differences were found between the two groups at T0 (p = .4723), while a significant difference was found at T24 (p = .0027). Quality of life showed a significant improvement in daily activities in the SPC group (p = .0033) compared to the infusion therapy group. No statistically significant changes in PTA thresholds were found in both groups between T0 and T24. CONCLUSION: The preliminary results of our study show a significant reduction of vertigo spells and a positive effect on tinnitus severity and on quality of life in patients with unilateral MD treated with SPC and when compared to patients treated with intravenous glycerol and dexamethasone. No effects on hearing thresholds were noted in both groups.

Real-life effects of benralizumab on allergic chronic rhinosinusitis and nasal polyposis associated with severe asthma.

The aim of this study has been to evaluate the efficacy of the IL-5 receptor blocker benralizumab on chronic rhinosinusitis with nasal polyposis (CRSwNP), associated with severe eosinophilic allergic asthma. Ten patients with severe eosinophilic allergic asthma and CRSwNP were enrolled. Sino-nasal outcome test (SNOT-22), numerical rating scale (NRS), endoscopic nasal polyp score, Lund Mackey CT (computed tomography) score, and blood eosinophil count were measured at baseline and after 24 weeks of treatment with benralizumab. All the above clinical, endoscopic, imaging, and hematological parameters significantly improved after 24 weeks of treatment with benralizumab. In particular, SNOT-22 decreased from 61.10 ± 17.20 to 26.30 ± 19.74 (P < 0.001), NRS decreased from 7.20 ± 1.55 to 3.40 ± 2.22 (P < 0.001), the endoscopic polyp nasal score decreased from 4.20 ± 1.32 to 2.50 ± 1.78 (P < 0.001), the Lund-Mackay CT score decreased from 16.60 ± 5.50 to 6.90 ± 5.99 (P < 0.001), and blood eosinophil count decreased from 807.3 ± 271.1 cells/µL to 0 cells/µL (P < 0.0001). These results strongly suggest that benralizumab exerted a very effective therapeutic action on CRSwNP associated with severe asthma, thus improving nasal symptoms and decreasing polyp size.

Intrinsic Laryngeal Lipoma Treated with Transoral CO2 Laser Microsurgery: An Unusual Case Report.

BACKGROUND Lipomas, the most common soft tissue tumors, represent almost half of all benign mesenchymal neoplasms and are characterized by the absence of symptoms. However, if they grow in a laryngeal site, they can cause dyspnea and dysphonia which represents one of the major symptoms of benign laryngeal diseases (such as polyps or nodules); these symptoms are often the first symptom of neoplastic diseases. CASE REPORT We present a case of a 28-year-old female patient with a rounded pseudocyst neoformation located in the left aryepiglottic fold that partially hid the homolateral vocal cord and limited its mobility. Due to the site of the lesion and MRI images showing a well-capsulated neoformation without contrast enhancement, we decided to surgically remove it with a micro-laryngoscopic approach after an evaluation of the patient's upper airway by an anesthetist. This case demonstrates that a micro-endoscopic approach using transoral laser microsurgery for surgical excision was useful for removing the entire mass and avoiding relapses. CONCLUSIONS Laryngeal lipomas are benign and rare lesions, in particular intrinsic lipomas are uncommon, but, if they grow, they can cause life-threatening symptoms. In our case, a lipoma reached a size of around 2 centimeters and was not pedunculated, only a histopathological examination of the surgical specimens could provide a differential diagnosis against a lipoma-like liposarcoma. The use of Transoral Laser CO2 Micro-laryngoscopy (TLM) provided good management of a small intrinsic lipomas of the larynx, minimizing the potential for relapses.

Effects of the first three doses of benralizumab on symptom control, lung function, blood eosinophils, oral corticosteroid intake, and nasal polyps in a patient with severe allergic asthma.

Severe allergic eosinophilic asthma can be characterized by inadequate control, despite the regular use of high dosages of inhaled corticosteroids/long-acting ß2-adrenergic agonists combinations, and the very frequent utilization of oral corticosteroids. Therefore, under these circumstances, an add-on biological treatment with monoclonal antibodies directed against suitable molecular targets, involved in the pathobiology of type-2 airway inflammation, is very useful. Within such a context, our case report refers to a 46-year-old woman with severe allergic eosinophilic asthma and relapsing nasal polyps, not eligible to add-on biological therapy with omalizumab because of her very high serum levels of immunoglobulins E (IgE). She is currently under treatment with the humanized monoclonal antibody benralizumab (30 mg subcutaneous injection, administered every 4 weeks for the first three doses, and every 8 weeks thereafter), an eosinophil-depleting anti-interleukin-5-receptor biologic. Our patient experienced relevant clinical and functional improvements already after the first dose, and subsequently striking changes were recorded after the second and third doses, including remarkable increases in asthma control test scores and forced expiratory volume in 1 s values, associated with a complete depletion of blood eosinophils and the interruption of oral corticosteroid intake, as well as with the concomitant disappearance of nasal polyps after the second dose. In conclusion, this case study suggests that benralizumab can exert a very rapid and effective therapeutic action in patients with severe eosinophilic asthma and nasal polyposis.
